<p>Do Chemistry labs always last the complete 3.5 hours? I'm afraid my Psyc discussion is going to overlap.</p>
<p>They don’t <em>always</em> last the full time, but they usually do. You should plan on staying MORE than 3.5 hours because you might need to stay after lab to clean up, pick up graded lab reports, or talk to your TA. </p>
